IMPROVEMENT IN APPARATUS FOR DISINFECTING VESSELS.

Specication forming part of LettersPatent No. 42,4164, dated April 26, 1864.

To all whom it may concern,.-

Be it known that l, E. HALL GovaL, of the city of New York, in the State of New York,

have invented a certain new and useful iml cation show the means I use for disintectiug a vessel afloat, as at quarantine or in harbor, but, as is evident, other'means may be used for vessels under other circumstance, or for chambers, the means being adapted to the conditions of the occasion.

By these drawings a vessel, a, is shown, with a furnace or tire-box, b, a tubular boiler, c, with its smoke-stack d, Figure l being a view looking down upon the vessel, and Fig. 2 being a view by transverse section at the red line of Fig 1.

The products of combustion from the l'urnace will pass around the boiler and escape through the smoke-stack, and the boiler will be provided with the usual supply and escape pipes, safety-valve, gage, 85e.

It will beseen that the one end of the boiler is covered, e, the cover having attached to it an air tube or pipe, f, and that the other end ot' the boiler is also covered by a conicalshaped cover, g, having within it. a blower or exhauster, h. From the end of the cover g a pipe will be continued, as also from the end of the pipe f, which, in case the means are bein g applied to a vessel iioating, will, for the part at least, be elastic or india-rubber pipes, so

as to allow of the vessels motion by the waves wit-hout injuring the pipes. Both h e pipes will terminate in the vessel or chamber to be puried, and thus, when the apparatus is in operation and the vessel or chamber closed, the air will be drawn Vfroui the vessel, passed through the tubes ot'tlul boior; heated up to a high degree of heat, and disinfected and forced back into the vessel, the torce employed being sufficient to give that degree of compression to the heated air as shall nake it enter into all the recesses of the vessel or chamber.

In some instances thefire or heat may be I applied directly to the tubes or space for heating the vitiated airi. e., there will be n'o water around the tubes in which the air is heated, they being exposed to the tire ot' the furnace or tire-box b direct, and, ot' course, no cylinder or shell will be needed around the tubes. The degree of heat will in some cases be'higher than in others, due to the amount and character ot'the infection or contagion, and in some instances it may be deemed best to force into the vessel or chamber fresh air heated to a high degree, the one pipe then being open to the atmosphere, while the other will be open in the vessel or chamber, and the exit of the air from the vessel or chamber so regulated that the proper degree of compression ofthe air in the vessel or chamber will be maintained. In this way the infected air will be driven out ot the vessel. y

What I claim as my invention, and desire to secure by Letters Patent, is-

-Disiniecting vessels, chambers, Src., by forcing the highly-heated a1r into and circulating it through them, substantially as herein set forth.
